Trendyol/kediatR

This system is a Kotlin library implementing the Mediator pattern, designed to simplify command, query, and notification handling through a unified request interface. It provides high-performance handler resolution with caching and integrates seamlessly with major dependency injection frameworks, including Spring Boot, Koin, and Quarkus. The library also includes robust build infrastructure and comprehensive test fixtures to ensure reliability across different runtime environments.

Users can now use Kediatr with the Koin dependency injection framework. A new KediatRKoinProvider implementation allows the library to resolve dependencies from the active Koin instance, and a convenience helper (KediatRKoin.getMediator) is provided to build a Mediator configured for Koin.

The library now provides a new starter module for Spring Boot 4.x compatibility. This change introduces \KediatRAutoConfiguration\ and \KediatRSpringBeanProvider\ to automatically register the Mediator bean within the Spring context, replacing previous manual wiring approaches. The auto-configuration is registered via the standard Spring Boot \AutoConfiguration.imports\ file, allowing users to integrate the mediator pattern seamlessly in Spring Boot 4.x applications without additional setup.

The Spring Boot starters for both version 2.x and 3.x now include automatic configuration that registers the \Mediator\ and \KediatRSpringBeanProvider\ beans. These beans are conditionally created only if no existing bean of the same type is present, allowing users to integrate the mediator pattern without manual setup while still permitting override via custom beans.

The buildSrc module has been restructured to improve code reuse and maintainability. New helper functions (Helpers.kt) were added to simplify iterating over subprojects and filtering project collections based on parent names and exclusions. Additionally, a utility property (predef.kt) was introduced to extract plugin IDs from Gradle plugin dependency providers, streamlining plugin configuration across the build.

The library replaces the previous Command, Query, and CommandWithResult abstractions with a single unified \Request\<TResponse\>\ interface, allowing users to model both commands and queries through one consistent pattern. Correspondingly, \CommandHandler\ and \QueryHandler\ are replaced by \RequestHandler\, and the \Mediator\ now exposes a single \send()\ method for all requests, removing the need for separate command and query dispatching methods. This change simplifies the API and reduces boilerplate for users adopting the mediator pattern.

The Quarkus starter now delegates single-instance resolution to a new QuarkusTypeResolver, which leverages the Quarkus BeanManager to resolve beans and discover subtypes. This replaces the previous mechanism with a CDI-native approach, ensuring that dependency injection for MediatR commands and queries is handled directly by the Quarkus container.

The core mediator now unifies queries and commands under a single Request interface, replacing the previous separate Command and Query types. Handler resolution has been refactored to prioritize exact type matches over inheritance, ensuring that a handler registered for a specific command is selected before falling back to base-type handlers. To improve performance, the mediator now uses a CachedRegistry that caches resolved request handlers, notification handlers, and pipeline behaviors using thread-safe concurrent maps, eliminating repeated resolution lookups during runtime.

Added Koin integration tests for Mediator; Added test fixtures for Mediator command, query, and notification handling; Added tests for CachedRegistry performance and correctness; Unified Spring Boot test suite for Mediator functionality.

The project's Gradle wrapper has been updated to use Gradle 9.7.1. This change ensures that builds are executed with a consistent, specific version of the Gradle build tool, eliminating potential discrepancies caused by different local Gradle installations and leveraging the features and bug fixes present in this release.

gradle · high confidence

The build system has been restructured to use Gradle version catalogs (defined in gradle/libs.versions.toml) for centralized dependency management, replacing previous ad-hoc version declarations. This change updates the Kotlin compiler to version 2.4.20, Kotlin Coroutines to 1.11.0, Kotest to 6.2.5, JUnit to 6.1.3, Koin to 4.2.2, and Quarkus to 3.39.4. Additionally, the project now enforces a JDK 17 build toolchain while ensuring published main artifacts remain compatible with JDK 11, and configures Maven publishing with signing enabled.
